For what are you allowed to use the loudspeaker system when driving in regular traffic?

You are allowed to use the loudspeaker system in regular traffic primarily for safety and informational purposes. This includes transmitting traffic information from the radio to keep drivers informed about road conditions or hazards, and giving operational information, such as instructions related to the vehicle's operation or emergency announcements. Using the loudspeaker for entertainment, like playing music or entertaining passengers, is not permitted because it can distract the driver and other road users, compromising safety. The rule ensures that loudspeaker use supports safe driving and clear communication rather than causing distractions.
